70. I've had many discussions with pro-gunners, and they basically do not believe in science.

As you point out, there have been many studies linking gun ownership to increased rates of homicide and suicide, but trying to explain this to a pro-gun person is like trying to convince Glenn Beck that carbon emissions truly are causing temperatures to rise. They are full of conspiracy theories, and they will repeat talking points from gun blogs that claim to "refute" the peer-reviewed science.

The implication is clear: there really is no intellectually honest way to defend the current gun laws in the US. If there were, the "pro-gun progressives" on DU would be doing it. But you don't actually see that here. The pro-gunners are pretty much making the same arguments you'd read on FreeRepublic: that gun control is just a precursor to government tyranny, that the studies simply represent "anti-gun bias", that a gun is just a tool, etc.
